Crop header with lateral fingers and hood articulated

ABSTRACT

Crop header with lateral fingers and hood articulated which particular structure facilitates time reduction during the task of inspection of the transport commands or auger activations of the crop header thereby contributing to the rotation or turn of aforementioned lateral fingers, enabling an easy access to the commands or auger activations. In the machine the lateral fingers (A) and hood ( 8 ) are arranged in an articulated form in relation to the piece that contains the transport auger, and preferably, lateral fingers (A) and hood ( 8 ) articulate in a way that their longitudinal axles (A 1 ) are displaced on a substantial horizontal level.

TECHNICAL FIELD OF THE INVENTION

The present invention refers to a crop header with lateral fingers and hood articulated which particular structure facilitates time reduction during the task of inspection of transport commands or auger activations of the crop header thereby contributing to the rotation or turn of aforementioned lateral fingers, enabling an easy access to the commands or auger activations.

TECHNICAL FIELD AND PROBLEMS TO SOLVE

In relation to the related art of the present invention, it is not known any crop header that incorporates lateral fingers and hood turn able or articulated, which movement allows a better access to the activation mechanisms of the combine harvester auger.

Taking into account the difficulty for the access to these mechanisms, it is the main objective of this invention to provide a hood and lateral fingers with turn characteristics towards the header sides, facilitating in an execution form with a turning centre in the back end and of a simple lock trigger in the front end. This job lasts only some seconds.

DETAILED DESCRIPTION OF THE INVENTION

In FIG. 1 it can be observed the positioning of left lateral finger “A” of a crop header, located perpendicularly to the augers edge; wherein arrow “B” indicates the movement direction of aforementioned lateral finger A.

In FIG. 2, it is clearly shown how the longitudinal edge “A1”, being part of the lateral finger “A”, turns according to arrow “C”, making in its turn a horizontal substantial level, until it gets considerably lined up or symmetrical regarding the header's transporting augers edge (not shown).

The final positioning of aforementioned lateral finger “A” allows to have access to the action controls or commands of transporting auger “D”.

It can be observed how the piece or frame 7, fixed to the transporting auger's body or crop header, permits the rotation on the same hood 8 and of the lateral finger “A”.

FIG. 3 shows how the extended piece or trigger 1 manages the hood lock and lateral finger “A”, by joining bush 4 and thereby preventing the lifting or turn of hood 8 and finger A.

Slot 2, which is visible in FIG. 5, allows the entering of bush 4, which is tight with screw 3, therefore the regulation throughout slot 3 a is possible to be registered.

In FIG. 5, it is shown trigger 1 unlocked from the bush which is pressed by screw 3. The aforementioned trigger is fixed to an attaching articulated piece 1 a, which presents a locking device 1 b.

In FIGS. 6 and 7, it is shown coupled and uncoupled, the preferential form of the locking device's (1 b) attaching detail with axle box 4, therefore fixing the lateral finger “A” and hood 8 preventing its turn. It can be seen that screw 3 can be displaced throughout slot 3 a.

During its functioning, in order for the lateral fingers “A” to move sideways, (which is a movement showed in FIG. 2), with arrow “C”, hood 8 must be lifted by pulling the trigger, which makes the locking device 1 b to be uncoupled from bush 4, producing in that way the uncoupling of aforementioned bush 4 and slot 2. Therefore, allowing carrying out the lateral finger's turn “A” outwards from the header.

Likewise in FIG. 10, the coupling of hood 8 to piece 7 is shown, detailed in FIG. 8 and it is screwed to the crop header's lateral. Piece 7 which, through its bolt 5, is connected by putting bush 6 to hood 8. It is on this bolt 5 where hood 8 moves, enabling hood 8 turn sideways.

The aforementioned bush 6 is welded to piece 9, and this piece 9 being screwed to hood 8.

Having described and specified the nature and scope of the invention as well as the way to implement it. 

1. A crop header comprising: lateral fingers; an articulated hood; and wherein the lateral fingers and the hood are articulate with relation to a frame containing a transport auger.
 2. The crop header according to claim 1, wherein the lateral fingers and the hood are articulated in a form that its longitudinal axles are displaced on a horizontal level.
 3. The crop header according to claim 1, wherein the lateral fingers and the hood are articulate through a bush conformed in the hood and inserted in a bolt of a piece fixed to the crop header.
 4. The crop header according to claim 1, wherein the lateral fingers fix their movement through a trigger mechanism which is supported by an articulated piece in which a holding device is defined, which is tight to a bush adjustable in position by a screw.
